Specialization for Druid

[beev]

So I hit 30, yay hell level.. Anyways, I had a question on what I should have specialized in.

I plan on solo'ing my whole career if do-able and then eventually making a career out of powerleveling. So, should I do alteration which deals with snares/roots/ports/heals, or should I be doing Evocation?

I am currently at around 100 specialization in alteration so I will have to do the quest if I want to reset and switch if need be.

Let me know what you think. Thanks!
